MICHIGAN CITY — As part of the mayor’s safe community initiative, 27 people were arrested Friday, mostly for selling heroin and other drugs, police say.

About 30 additional people were arrested on a separate day, with more arrests planned, they add.

''You're going to see more activity from our narcotics task force,'' Michigan City Police Chief Mark Swistek said.

The department's narcotics division has grown from four to eight officers since September in a partnership with the state, the U.S. Drug Enforcement Agency and the U.S. Marshal's Office, he noted.

The idea is to make the community safer by reducing the availability of drugs, which often result in crimes like burglaries and thefts to feed addictions, Swistek said.
